The Oslo team has moved all previously incubated code from the
openstack/oslo-incubator repository into separate library
repositories and released those libraries to the Python Package
Index. Many of our official project teams are still using the old,
unsupported, incubated versions of the code. The Oslo team has been
working to remove that incubated code from projects, and the time has
come to finish that work.

The stable team doesn’t have any code repositories and therefore has
nothing to do. It could be argued that the stable team is responsible for
the stable branches of all projects but nature of the stable projects
precludes code refactors.

The octavia project does not use oslo incubator and the last references
were removed in the patch listed below.
Technically this was done while we were part of neutron, but documenting
here for clarity.
